Graphics flash in a checkered pattern

[bls1999]

Describe the bug
In a few games I've tested, there's an odd graphical glitch that looks like a checkerboard is flashing on the screen. Here's a video of what I'm talking about.

Games Shown:

• Kimblis the Blue (Game Link | SWF Link)
• The Game of Disorientation (Game Link | SWF Link)
• Red Earth (Game Link | SWF Link)

Expected behavior
The graphics should be displayed without flashing.

Is the problem with the Ruffle desktop app, extension, or self-hosted version?
Self-hosted version, nightly 2021-02-03.

What platform are you using?
Desktop -- Brave Browser, Mac OS X Mojave.

I'm not seeing this problem anymore in Red Earth - can you confirm that the problem is fixed?
I can't check Kimblis the Blue because I can't get the game to work at all in Ruffle. All I see is a fog animation, not the actual menu.

Kimblis the Blue needs the 'overlay' blend mode (#58). With #8262, it looks great!

@bls1999 asking again now, is the checkerboard graphics problem fixed for you?

Seems to be! I'll re-open if it appears again. Thanks for circling back!
